Note: The type of thread policy determines the Priority that can be
assigned to the thread, as indicated in the third column of the
table above.

The above means that Kylix also ignored setting the thread priority on
Linux for regular processes/threads (since the only allowed value for
SCHED_OTHER was "0").
Even if a API is not portable between *nix, at least we can
implement it
per platform, and hopefully create some abstraction layer on top of
that,
or translate TThreadPriority type to the individual platform
implementations. FPC has many API's implemented that are not portable
between platforms - so this should not be a stopping block.
That's why I added "I'm not even sure about what the low level APIs
are on particular Unix platforms such as Linux and Mac OS X".
